Comment
; Beginning of the definition of a ;non-periodic curve
table with number 3.
; 1st motion operation, defines the starting values and
1st intermediate point:
Master value: 0, Following value: 0
; 2nd intermediate point
Master value: 0...20, Following value: starting value...0
; 3rd intermediate point:
Master value: 20...100, Following value: 0...6
; 4th intermediate point:
Master value: 100...150, Following value: 6...6
; 5th intermediate point:
Master value: 150...180, Following value: 6...0
; End of definition. The curve table is generated in
its internal representation as a polynomial of up to
the 5th order. The calculation of the curve
definition with the specified intermediate points is
dependent on the modally selected interpolation type
(circular, linear, spline interpolation). The part
program state before starting the definition is
restored.
